fullygruntled 09-28-2006, 01:33 PM 20R motor in a 1980 truck. Has spark, delivers fuel, plugs (at least plug #1) OK, static timed just in case. Turns and turns and turns and turns, no fire, even under ether. What other shinto mojo need I concern myself with on this? Hawaii500_1999 09-29-2006, 08:58 PM next step? compresion. test all 4 cyliders and get back to us. fullygruntled 10-02-2006, 01:01 PM Only "tested" #1 (got enough pressure to static time it). You sure it needs compression on all 4? :laughing: Hawaii500_1999 10-03-2006, 09:34 PM yup. the basic things needed to run an engine is: -fuel -air -ignition -compresion. and it sounds as if you already checked the fuel and ignition. fullygruntled 10-04-2006, 07:16 AM Compression not super-even, but present on all cylinders. YamanX 10-05-2006, 08:22 AM You checked to make sure all plugs are firing? Carbed or FI? fullygruntled 10-05-2006, 12:43 PM You checked to make sure all plugs are firing? Carbed or FI? At least to the plug, yes. Plugs didn't look that bunged up (albeit carbon-fouled). carbed, BTW YamanX 10-05-2006, 05:27 PM So do they all have spark? fullygruntled 10-06-2006, 10:52 AM Yes. In short, I HAVE checked all the simple applies-to-any-motor things I could think of... I was hoping to discover if there were any quirks to Toyota that might prevent it from running if essentially everything else seems to be in working order. bremen242 10-07-2006, 06:33 AM Yes.

DoctorDuke 10-07-2006, 08:40 PM How about a little backround. Did it just not start oneday? Or was this after something else was fixed? Was it acting different before? | |
